You will go to need only of a cable USB, if not recorded an image Linux in a card SD,
recommend that it do, as the image that comes in galileo is not able to retain sketch.
Port for uploads used in Galileo is the micro USB (USB Client)
Ths USB client is the one that has a microUSB port. You can use this port to interact with the Arduino IDE. [Remember to always use a power supply before plugging a USB cable in this port]
I currently have my raspberrypi on wifi and am connecting to it via remote terminal, and also using weaved service (external IP access).
I would like to do this same thing with the Galileo. I think I might have to get it up and running on wifi first through the arduino micro-usb connector, then I can set up the remote SSH connection.
Thanks a lot.
Just as a follow up,
I did avoid purchasing the 6-pin cable by running an arduino code first (here: Linux Tutorial For Intel® Galileo Gen 2). I now can access the Galileo via Putty.
I then ran the blinking LED C++ program from Eclipse and it appeared to work.
Hopefully I wont have any issues using this method.
